Page 4: Introduction
Introduction The MF300H+ Magnetic Field Meter is used to measure the intensity and the direction of magnetic fields. The meter can be used to show the actual value of the intensity of the magnetic field as an average, peak or RMS value. The measured values can be presented in a range of units and the chosen options can be selected from a menu displayed on the... -

Page 10: Samples
Operation - Logger 5.3 Samples This allows the number of samples to be selected for RMS mode. In this mode, samples are taken, squared and summed. Finally they are averaged and the square root taken. The normal setting is 64, but options are 4,16, 64 and 256 available. The number of samples controls time response of the instrument in RMS mode. -

Operation - Logging Step 8 Logging mode From the set up menu select Logger. 8.1 Review This presents the logged data in groups of 4 to the extent of the logger database. You can scroll through the data with the up/down keys. Any other key exits. Data is stored as a x10 integer i.e. -
Page 13: Magnetic Particle Inspection
Operation - MPI Magnetic Particle Inspection A wide range of magnetising systems are used for Magnetic Particle Inspection. The value of the magnetic flux density required is specified in BS4069 as 0.72 Tesla. This is produced when the magnetising coils generate a magnetic field of 2.4kA/m which is applied to a component made from material with a relative permeability of 240. - Page 14 Page 14...
